Description

本発明は、特許請求項１の前提部に従うハイブリッド車両に関する。   The present invention relates to a hybrid vehicle according to the premise of claim 1.

本特許出願において「ハイブリッド車両」との概念は、車両が１個の燃焼機関式の駆動装置と少なくとも１個の電気機械とを有し、この電気機械が制動エネルギーを発電機として回生し、燃焼機関式の駆動装置を多くの稼動状態で電動機として支援する又は車両を多くの稼動状態で純粋に電動機として駆動するために設けられているという車両として理解される。   The concept of “hybrid vehicle” in this patent application is that the vehicle has one combustion engine type driving device and at least one electric machine, and this electric machine regenerates braking energy as a generator and burns. It is understood as a vehicle that is provided to support an engine-type drive as a motor in many operating states or to drive a vehicle purely as a motor in many operating states.

本発明の課題は、使用可能状態にある出力能力が出来るだけ良好に現在の出力要求に適合されているハイブリッド車両を創作することである。   The object of the present invention is to create a hybrid vehicle whose output capability in a usable state is as good as possible adapted to the current output requirements.

前記の課題は、特許請求項１の構成要件により解決される。本発明の有利な形態と他の構成は下位請求項に記載されている。   The above-mentioned problem is solved by the constituent requirements of claim 1. Advantageous forms and other configurations of the invention are described in the subclaims.

本発明の出発点は、第１クラッチ装置を介して変速機と連結可能である燃焼機関式の駆動装置と、電気機械とを有するハイブリッド車両であり、この際、変速機は選択的に
− 燃焼機関式の駆動装置によってのみ駆動可能である、又は、
− 燃料機関式の駆動装置により及び電気機械により同時に駆動可能である、又は、
− 第１クラッチ装置が開かれている場合、電気機械によってのみ駆動可能である。 The starting point of the present invention is a hybrid vehicle having a combustion engine-type drive device that can be connected to a transmission via a first clutch device, and an electric machine. Can only be driven by an engine-type drive, or
-Can be driven simultaneously by a fuel engine drive and by an electric machine, or
If the first clutch device is open, it can only be driven by an electric machine;

本発明の核は、燃焼機関式の駆動装置が少なくとも２個の燃焼機関ユニットを有することにあり、つまり第１クラッチ装置を介して変速機と連結可能である第１燃焼機関ユニットと、第２クラッチ装置を介して第１燃焼機関ユニットと連結可能である第２燃焼機関ユニットである。   The core of the present invention is that the combustion engine type drive device has at least two combustion engine units, that is, a first combustion engine unit that can be connected to a transmission via a first clutch device, and a second The second combustion engine unit is connectable to the first combustion engine unit via a clutch device.

平均的な出力要求だけが存在する稼動状態では車両は第１燃焼機関ユニット及び／又は電気機械によってのみ駆動され得る。例えば高速の高速道路走行時のようにより高い出力が必要とされる場合には第２燃焼機関ユニットが作動される。   In an operating state where only an average power demand exists, the vehicle can only be driven by the first combustion engine unit and / or the electric machine. For example, when a higher output is required, such as when traveling on a highway, the second combustion engine unit is operated.

両方の燃焼機関ユニットは例えば各々につき２個のシリンダを備えた「燃焼機関（内燃機関）」であり得る。しかし個々の燃焼機関ユニットのシリンダ数は同じである必要はなく異なっていてもよい。   Both combustion engine units can be, for example, “combustion engines (internal combustion engines)” with two cylinders each. However, the number of cylinders in each combustion engine unit need not be the same and may be different.

このようなハイブリッド車両は多数の稼動状態で稼動され、以下の稼動状態をとることができる。例えば：
− 稼動状態１では両方の燃焼機関ユニットがオフにされていてハイブリッド車両は電気機械によってのみ駆動される。
− 稼動状態２では第１燃焼機関ユニットがオンにされていて第２燃焼機関ユニットがオフにされている。この稼動状態では車両は第１燃焼機関ユニットによってのみ、そして電気機械が作動されているのであれば電気機械により駆動され得る。
− 稼動状態３では両方の燃焼機関ユニットがオンにされている。この稼働状態では車両は、燃焼機関として使用可能状態にある全出力を用い即ち両方の燃焼機関ユニットにより、そして電気機械が作動されているのであれば電気機械により駆動され得る。 Such a hybrid vehicle is operated in a number of operating states, and can be in the following operating states. For example:
In operating state 1 both combustion engine units are switched off and the hybrid vehicle is driven only by the electric machine;
In operating state 2 the first combustion engine unit is on and the second combustion engine unit is off; In this operating state, the vehicle can be driven only by the first combustion engine unit and, if the electric machine is operated, by the electric machine.
-In operating state 3, both combustion engine units are switched on. In this operating state, the vehicle can be driven with full power, ie both combustion engine units, ready for use as a combustion engine, and with the electric machine if the electric machine is operated.

電気機械を制御するためには適切な電子装置が設けられている。本発明の更なる構成では、稼動状態２から稼動状態３への移行時、即ち第２燃焼機関ユニットのスタート時には電気機械が少なくとも短期的に駆動トルクを生成し、この駆動トルクが第２燃焼機関ユニットのスタートを支援することが意図されている。好ましくは電気機械は第２燃焼機関ユニットのスタート時、少なくともそのスタート過程に必要な出力が補われ且つ変速機入力における（一時的な）トルク低下が回避されるように電動機として生成されるトルクを提供する。   Appropriate electronic devices are provided to control the electric machine. In a further configuration of the invention, the electric machine generates a drive torque at least in the short term at the time of transition from the operating state 2 to the operating state 3, i.e. at the start of the second combustion engine unit. It is intended to help start the unit. Preferably, when the second combustion engine unit starts, the electric machine generates torque generated as an electric motor so that at least the output required for the start process is supplemented and a (temporary) torque drop at the transmission input is avoided. provide.

本発明の更なる構成では電気機械は惰行稼動時にも発電機としての負荷トルクにより第２燃焼機関ユニットの連結及び連結解除時の減速動向を補整する。   In a further configuration of the present invention, the electric machine compensates the deceleration trend at the time of connection and release of the second combustion engine unit by load torque as a generator even during coasting operation.

電気機械は特に第１燃焼機関ユニット用のスタータとしても使用され得る。   The electric machine can also be used in particular as a starter for the first combustion engine unit.

本発明の基本原理を示す概要図である。It is a schematic diagram which shows the basic principle of this invention.

次に本発明を図面と関連して詳細に説明する。   The invention will now be described in detail in connection with the drawings.

図１はハイブリッド車両の駆動トレイン１を示していて、この車両は燃焼機関式の駆動装置２と電気機械３とを有す、電気機械３はここでは変速機６の変速機ハウジング５の変速機鐘形部４内に配置されている。   FIG. 1 shows a drive train 1 of a hybrid vehicle, which has a combustion engine type drive 2 and an electric machine 3, which is here a transmission of a transmission housing 5 of a transmission 6. It is arranged in the bell-shaped part 4.

燃焼機関式の駆動装置２は第１燃焼機関ユニット７と第２燃焼機関ユニット８により形成されていて、これらの燃焼機関ユニットは共通の機関ハウジング内に格納され得る。両方の燃焼機関ユニット７、８は各々に個別のクランクシャフト７ａ、８ａを有する。両方の燃焼機関ユニット７、８は同じシリンダ数を有する又は異なるシリンダ数を有するユニットであり得る。例えば燃焼機関ユニット７及び燃焼機関ユニット８は各々につき「２シリンダ機関」であり得る。   The combustion engine type drive device 2 is formed by a first combustion engine unit 7 and a second combustion engine unit 8, and these combustion engine units can be stored in a common engine housing. Both combustion engine units 7, 8 each have a separate crankshaft 7a, 8a. Both combustion engine units 7, 8 can be units having the same number of cylinders or different numbers of cylinders. For example, the combustion engine unit 7 and the combustion engine unit 8 may each be a “two cylinder engine”.

図１から見てとれるように燃焼機関ユニット７は第１クラッチ９を介して変速機６の入力シャフト１０と接続されている。変速機６の入力シャフト１０には相対回転不能に電気機械３のロータ１１が接続されている。つまりクラッチ９が閉じられている場合、変速機６は第１燃焼機関ユニット７により、そして電気機械３が作動されるのであれば電気機械３により駆動され得る。   As can be seen from FIG. 1, the combustion engine unit 7 is connected to the input shaft 10 of the transmission 6 via the first clutch 9. The rotor 11 of the electric machine 3 is connected to the input shaft 10 of the transmission 6 so as not to be relatively rotatable. In other words, when the clutch 9 is closed, the transmission 6 can be driven by the first combustion engine unit 7 and by the electric machine 3 if the electric machine 3 is operated.

電気機械３は制動過程中に制動エネルギーを回生するため即ち機械エネルギーを電気エネルギーに変換するために使用され得る。この稼働状態では電気機械３は変速機入力シャフト１０により駆動される発電機として動作する。   The electric machine 3 can be used to regenerate braking energy during the braking process, i.e. to convert mechanical energy into electrical energy. In this operating state, the electric machine 3 operates as a generator driven by the transmission input shaft 10.

追加的に電気機械３は第１燃焼機関ユニット７用の始動器即ちスタータとして使用され得る。クラッチ９が閉じている場合、例えばバッテリやコンデンサであるここでは非図示のエネルギー蓄積器により給電され、第１燃焼機関ユニット７が電気機械３によりスタートされ得る。   In addition, the electric machine 3 can be used as a starter or starter for the first combustion engine unit 7. When the clutch 9 is closed, the first combustion engine unit 7 can be started by the electric machine 3 by being fed by an energy storage (not shown) such as a battery or a capacitor.

両方の燃焼機関ユニット７、８の両方のクランクシャフト７ａ、８ａの間には第２クラッチ１２が配置されている。両方のクラッチ９、１２が閉じられている場合、変速機６は両方の燃焼機関ユニット７、８により同時に、そして電気機械３が作動されているのであれば電気機械３により駆動され得る。   A second clutch 12 is disposed between both crankshafts 7a, 8a of both combustion engine units 7, 8. If both clutches 9, 12 are closed, the transmission 6 can be driven by both combustion engine units 7, 8 simultaneously and by the electric machine 3 if the electric machine 3 is activated.

第２燃焼機関ユニット８のスタート時、トルク低下、従って車両の速度低下或いは加速度低下を回避するために、スタート進行中には第２燃焼機関ユニット８用のスタートトルクが電気機械３により補われ得る。   When the second combustion engine unit 8 is started, the start torque for the second combustion engine unit 8 can be supplemented by the electric machine 3 while the start is in progress in order to avoid a torque drop, and hence a reduction in vehicle speed or acceleration. .
